the vac -m bug is fixed. (it was fixed earlier tonight, i just forgot to push the fix to cvs.)
if you use vac -m to manage a dump-like tree of backups, you will likely be interested in the new -a flag, which automates the process. also, -e takes glob patterns now, and -x will read patterns from a file. these changes are not yet in the plan 9 vac. thanks to michael kaminsky for suggesting them. russ
